ABSTRACT:
An access plug flange is provided for inspection ports, for example on high temperature chemical processing vessels or pipes. The plug flange prevents heat loss through an access port formed in an insulative lining covering the vessel or pipe. The plug flange further does not deteriorate or lose its sealing effect despite its location near relatively high temperatures.
